The spooling area,
i
u,r/ '1'001/ uucp, contains the following important files and directories:
/usr/spooljuucp/C.
/usr/spool/uucp/D.
/usr/spoolluucp/D.ho,tntJme
/usr/spool/uucp/LOGFILE
/ usr / spool/ uucp /SYSL OG
directory for command, "C." files
directory for data, "D.", files
directory for local "D." files
log file of uucp activity
log file of uucpfile transfers
Note that
C.,
D.,
and
D.ho,tntJme
are subdirectories, unlike earlier implementations ofuucp. In
older versions,
C.
and
D.
files are placed directly into the spooling directory,
/u,r/,pool/uucp;
in
the current version, they are placed in their appropriate subdirectory. So, in the old version
you'd have, say, / u,r/ '1'001/ uucp/
C.re,45n0091;
in the new version the file would
be
/ u,r
1'1'001/ uucpl
C./ C. re,,l 5n 0091.
As uucp operates it creates (and removes) many small files in the directories underneath
/ u,r/ '1'001/ uucp. Sometimes files are left undeleted; these are most easily purged with the
uucletJn
program. Instructions in the
uUCp.titJlI
file take care of doing this daily clean-up for you.
The uucp log files can grow without bound unless trimmed back;
uulog
is used to maintain these
files.
uucp.titJlI
and
uucp.week
manage this housekeeping. If you decide to prune these direc-
tories yourself,
be
careful: randomly removing files from / u,r/ '1'001/
uucp
may cause
uucp
to gen-
erate error messages when it tries to access a file another file claims is there. (For instance, each
mail transaction creates three files. ) You do, however, need to clean the / u,r / '1'0011
uucppublic
directory 'manually'; this is a place for people at other sites to send to when sending files to
